Exposure index, or EI, refers to speed rating assigned to a particular film and shooting situation, and used in the exposure meter or equation, to compensate for equipment calibration inaccuracies or process variables, or to achieve certain effects.

EXPOSURE INDEX or EI - A number that indicates a film's effective speed.

Exposure index ( EI ) A film speed rating similar to an ISO rating abbreviated EI. When film is shot at something other than its rated speed setting, or ASA, The speed setting at which it is exposed is referred as the Exposure Index.

Exposure index (EI). Numeric description indicating the recommended sensitivity setting for a specific type of film and also the film sensitivity setting on a camera.

exposure index a number assigned to a photographic material to relate its speed to other photographic materials.

Exposure index - see Speed. Exposure latitude - amount by which it is possible to over or underexpose a light sensitive material and, with standard processing, still produce acceptable results.

EI/ASA, Exposure Index A numerical designation of a film's sensitivity to light. The current US standard for film speed. See: ISO; and DIN.

FAST FILM-Photographic material of relatively high sensitivity to light, having a high-exposure index. (PIA) FIELD-Scanning lines in one half of one video or television frame. There are two fields (one odd, one even) in a frame. One field equals 262.

By referring to the exposure index in the viewfinder and working in stops, you can fine tune your exposure. Use manual focus for stationary objects. You can pick the best focus point for maximum depth-of-field.

To those who say about traditional B&W films "X is too flat, Y is too contrasty": manufacturer's development times and exposure indexes are just starting points.

I have had success in the solarization of 35- mm Ektachrome 100 Plus film that was exposed using the normal, recommended exposure index of 100.

Set your exposure meter for an initial exposure index of 8 and bracket your exposures in 1/2 stop increments to plus and minus 1 stop. Keep all exposures between 1 and 8 seconds.

(Evaluative-Through The Lens) An exposure system that uses a brief pre-flash before the main flash to calculate the exposure index (used by Canon®). EXIF ...

E-TTL - Canon's Evaluative-TTL exposure system that uses a brief pre-flash before the main flash to calculate the exposure index.

understandable as exposure methods vary greatly not only between types of film, but also the cameras in which the film is used. Added to this, there is a great deal of misinformation about such considerations as film ISO (speed), EI (exposure index) ...
